[Elecraft] K3 FIRMWARE UPDATE REQUIRED if you have an Elecraft 2.7 kHz crystal filter

[David Ferrington, M0XDF]

I'll need that announcement mail, since I use a Mac to interface to my rig.
I have a wintel laptop and will use that for updates, but its only on when
it has to be.

I think computer viruses should count as life. I think it says something
about human nature that the only form of life we have created so far is
purely destructive. We've created life in our own image.
